Description
図1は、本実施の形態に係る流体取扱装置としてのマイクロ流路チップの形状を示す図である。図1(A)は平面図、図1(B)はA−A線正面断面図、図1(C)は底面図、図1(D)はB−B線左側面断面図である。なお、図1(A)、図1(B)には、電極棒1a、1bをともに示す。
まず、マイクロ流路チップ10において、第1領域(注入口)23a’に泳動液を注入し、流路22’を充填する。次に分析用の試料を注入する。また、電極棒1a、1bを、第2領域24a’、24b’に挿入して導電性接着剤26a、26bに接触させる。
図4は、図1(A)のE−E線拡大断面図である。図4に示すように、カーボンインクの16b(16a)の厚みに起因して、フィルム14のカーボンインクの16b(16a)の周辺部分がチップ本体12に未接着となり(ラミネート不良)、カーボンインクの16a(16b)の縁部において、チップ本体12とフィルム14との間に隙間31a、31bが生じる虞がある。
以下、本実施の形態に係るマイクロ流路チップのバリエーションについて説明する。
図5は、本実施の形態に係るマイクロ流路チップのバリエーション1の形状を示す図である。バリエーション1のマイクロ流路チップ10−1は、試料をヒータで加熱するために用いられる。図5(A)は平面図、図5(B)はF−F線正面断面図、図5(C)は底面図である。なお、図5(A)、図5(B)には、電熱ヒータ1a−1をともに示す。なお、図5において、図1と共通する部分には、同一の符号を付して詳しい説明を省略する。
